SPOOL-MOLDING MACHINE.

No event-4.

To allwhom it may concem:

Be it known that I, VVILLIAM BURKE, a

- citizenof the United States, and residing at simp e in constructionand operation and by ,means of which the material is thoroughly packedand compressed and all moisture or Water expelled therefrom, and bymeans of WlllCltS ools or similar articles may be convenient y andrapidly made at a minimum of cost.

The invention is fully disclosed in the lollowing specification, ofwhich the aceom panying drawin forms a part, in which the separate partso 111 ii rovenient are designated by suitable reielence char cters ineach of the views, a d in s eh;

zontal mold cylinder 6 provided in the top and bottom thereof, in theform of construe tion shown, with tubular inlets b and b, the latterwhich is at the bottom of the' nold cyl inder being provided with avalve 5 Mounted in the top portion of the left hand upright a of themain frame is a horizontally movable plunger 0, and mounted in the top\portion of the right hand upright a of the main frame is a horizontallymovable plunger d and the inner ends of these plungers are adapted toenter and move in the opposite end portions of the mold cylinder 6 andsaid mold cylinder t is also adapted to slide on said plungers or on theright hand plunger 65, which, as will be seen, is much longer than theleft hand plunger c. v

The right hand plunger d, in the form of construction is provided with acentral longitudinal bore d which opens through the inner end thereofand in which is placed a longitudinally movable and adjustable rodprovided at its outer end with a pin a which passes up through alongitudinal slot d 1n the plunger (5 and by means oi w *h the positionof the rod 6 may be adjusted, and said pin 0 is provided ith a' nut c"for this purpose.

The mold cylinder 5' is provided in the top th reef and in the oppositeend 1101 is thereol with hoppers or other suitable dc vices f throughwhich the pulp from which the spools are made may be discharged into theopposite end portions of the mold cylinder t and placed in the moldcylinder 2; the mold proper as shown at g, the mold proper is shown insection in Fig. 3 and in detail in Figs. 5, 6, 7 and 8 and said mold iscylindrical in cross section and oblong in form and the dimensionsthereof will depend on the dimensions of the s Y ool or spools which itis desired to form. T 1e said mold is cylindrical in cross section andcom osed of separate longitudinal parts g as 0 early shown in Figs. 6, 7and 8, and each of said parts is provided with a dowelin g. and acorrespondingrecess g, and the dowel-pin or pins g of one part enter therecess or recesses g of another art and hold the se arate arts of the11101 together. The mo d is a so provided with a longitudinal bore 9 theend portions of which are beveled as shown at g,

g at the ends thereof form the spool in the scribed. The mold g is alsoenlarged at the and the'central bore g and beveled portions operation ofthe device as hereinafter de liquids into and through the discharge pipethe annular chamber h, and if the annular bead g is employed, the saidannular chamber will be divided into two parts as will be readilyunderstood, and the said annular bead, when employed, is madesufliciently narrow to not interfere with the passage of connections 6and b The annular rib g is only intended, however, to strengthen thebody portion of the mold, and the mold may be made ofsuflicient'strength to render said bead unnecessary.

Connected with the outer ends of the plungers c and d are crank rods 71eccentrically connected with worm gears i which i are mounted in thesame vertical plane longitudinally of the main frame, and in the centralbottom ortion of the main frame is a longitudina shaft 7' provided atits opposite ends with worms j and by turning the shaft the plungers-cand d may be moved inwardly or outwardly according to the direction inwhich said shaft is turned. The shaft j, in the form of constructionshown, is provided with a belt wheel 1' by which it may be operated ifdesired, or said shaft may be turned by means of a crank or in any othermanner.

The late I) which constitutes the base plate of the mold cylinder b isprovided at one side with an upright member is with which is connected apin W, and pivoted to i the base plate or member a of the main frame isa lever m providedw-ith a longitudinal slot m through which the pin kpasses and by means of this construction the mold'cylinder may, as willbe understood, be moved longitudinally of the main frame, in eitherdirec tion. 1

The normal position of the parts of the ap- 1 paratus or machine is thatshown in Figs. 1,

2 and 3, and .Whenever it is desired to mold a s 001, the aper or otherfibrous 1pulpin a p astic or l1quid condition is poure mold cylinder 6through the ho pers, funnels or other devices f. The sha t j is thenturned so as to force the plungers c and d inwardly and the fibrous pulpin the opposite ends of the mold cylinder 6* is forced into the mold g.It will be understood, of course, that the movement of the plungers cand d is a reciprocating movement, and this operation may be'repeateduntil the-mold g v1s into the compactly filled with pulp. In this opera:tion the liquid or moisture in the pulp is mold 9 into the chamberaround said mold and passes out through the discharge pipe connectionsI)? and Z1. vantageous to close the pipe 6 at the bottom of the cylinderso as to prevent the-water or moisture from the pulp from passing outtherethrough and retain a quantity thereof in the cylinder until thespool is completely formed in the mold after which the valve 6 maybe'open and the chamber 7 drained.

When the operation of forming a spool is fully completed the plungers cand d are Withdrawn into the position shown in Fig. 3, the

lever m is operated so as to throw the. mold cylinder b into theposition shown in dotted lines in Fig. '3, and in this operation themold g with the spool therein is'discharged at the opposite end of themold cylinder 1). The plunger "0 is provided atits inner end with arecess 0 adapted to receive one end of the rod 2, and the object of therod 6 is to form the operation of the apparatuses hereinbeforedescribed. 7, After the mold with the spool therein has been dischargedfrom the mold cylinder as above described, the separate parts of themold maybe disconnected and the spool removed therefrom as will bereadily understood.

The movement of the plate I) which carries the cylinder 6 as abovedescribedmay be efiected by the lever' m or by turning the nection withthe rack b on the bottom of the plate 7) but the said cylinder may bemoved longitudinally, or into the difierent necessary positions thereof,by any suitable means. If the shaft a is employed for this purpose,however, an ordinary crank may be connected therewith. My invention isnot limited to the exact construction, combination and arrangement ofthe various parts of my improved machine as herein shown and described,and various changes therein and modifications thereof may be madewithout departing from the scope of my invention as set out in theappended claims.

Having fully described my invention, what I claim as new-and desire tosecure by Letters Patent, is i 1.

3. In a spool-molding machine, a frame, a mold cylinder movablelongitudinally thereof, horizontal plungers mounted in the frame andadapted to operate in the cylinder, means for feeding material into theopposite ends of the mold cylinder, and a spool mold mounted in the moldcylinder and movable longitudinally thereof, one of said plungers beingalso provided with a rod. which passes centrally through the spool mold,said spool mold and said mold cylinder being provided With means fordischarging liquid therefrom when the pistons are moved inwar 1 4. In aspool molding machine, a frame, a mold cylinder movable longitudinallythereof, horizontal plungers mounted in the frame and adapted to operatein the cylinder, means for feedlng material into the opposite ends ofthe mold cylinder, and a spool mold mounted in the mold cylinder andmovable longitudinally thereof, one of said plungers being also providedwith a rod which passes centrally through the spool mold, said spoolmold and said mold cylinder being provided with means for dischargingliquid therefrom when the pistons are moved inwardly, and said spoolmold being composed of separate longitudinal parts detaohably connected.
